Bright Start研究的目的是开发和测试学校环境干预的有效性，并辅以家庭参与，通过增加幼儿园和一年级美国印第安儿童的体育活动和健康饮食习惯来减少体重过度增加。“光明的开始”是一项分组随机、以学校为基础的试验，涉及南达科他州松岭保留地14所学校的454名儿童。孩子们从幼儿园开始到一年级结束都被跟踪。主要结果变量为平均BMI、平均体脂百分比和超重/肥胖儿童的患病率。干预的目标是：增加在学校的身体活动，每天至少60分钟;修改学校的膳食和零食;并参与家庭在家里的行为和环境的变化。在基线时，32%的男孩和25%的女孩超重/肥胖。虽然干预与BMI，BMI-Z，皮褶或体脂百分比的平均水平的统计学显著变化无关，但干预与超重患病率的统计学显著净下降10%相关。干预组儿童的超重发生率为13.4%，而对照组儿童的相应发生率为24.8%;差异为-11.4%（P= 0.033）。干预措施显着降低了父母报告的含糖饮料，全脂牛奶和巧克力牛奶的平均儿童摄入量。学校体育活动持续时间的变化不显着。由于肥胖是当今美国印第安儿童面临的最严峻的健康挑战，因此需要进行更多的干预研究以确定有效的方法。
The aim of the Bright Start study was to develop and test the effectiveness of a school environment intervention, supplemented with family involvement, to reduce excessive weight gain by increasing physical activity and healthy eating practices among kindergarten and first‐grade American Indian children. Bright Start was a group‐randomized, school‐based trial involving 454 children attending 14 schools on the Pine Ridge Reservation in South Dakota. Children were followed from the beginning of their kindergarten year through the end of first grade. Main outcome variables were mean BMI, mean percent body fat, and prevalence of overweight/obese children. The goals of the intervention were to: increase physical activity at school to at least 60 min/day; modify school meals and snacks; and involve families in making behavioral and environmental changes at home. At baseline, 32% of boys and 25% of girls were overweight/obese. Although the intervention was not associated with statistically significant change in mean levels of BMI, BMI‐Z, skinfolds or percentage body fat, the intervention was associated with a statistically significant net decrease of 10% in the prevalence of overweight. Intervention children experienced a 13.4% incidence of overweight, whereas the control children experienced a corresponding incidence of 24.8%; a difference of −11.4% (P= 0.033). The intervention significantly reduced parent‐reported mean child intakes of sugar‐sweetened beverages, whole milk, and chocolate milk. Changes in duration of school physical activity were not significant. Because obesity is the most daunting health challenge facing American Indian children today, more intervention research is needed to identify effective approaches.
